Yes that's right, is a private node using route hints and trampoline channels. That's not a real issue here. The issue is that I do not understand why a channel with a capacity of 62k sats and with almost 10k sats still available to receive, can't receive a damn payment of 1k sats.

The only explanation I could see in this are the commit_fees, that vary depending on the onchain fees. But at least the UI of the app should inform better the user, displaying a REAL "can receive" amount. Right now is really confusing and many users will just open a shit ton of small channels instead of refilling better those existing ones.
